Why is a women consciously contracting her uterus when she pushes?

Women do not consciously contract their uterus when they push during childbirth. Instead, the uterus contracts involuntarily due to hormonal signals and the pressure of the baby's head on the cervix. The pushing effort that a woman exerts during labor is primarily focused on expelling the baby through the birth canal by contracting her abdominal muscles and using her diaphragm to bear down. The uterine contractions, also known as labor contractions, are regulated by the body's natural hormones, particularly oxytocin, which stimulates the uterine muscles to contract.
